摘要： The positive electrode active material of the present invention is characterized in that its main component is a lithium metal oxide, and the lithium concentration at the surface portion of the primary particles that make up the active material is lower than that in the interior thereof. There will be less increase in internal resistance with a secondary cell made using this active material. The above-mentioned active material can be manufactured, for example, by bringing the raw active material into contact with a treatment liquid containing metal ions, and thereby lowering the lithium concentration at the surface portion of the primary particles that make up the raw active material.

摘要： In a nonaqueous electrolyte rechargeable battery in which a positive electrode plate (1) and a negative electrode plate (2) are superimposed with a separator (3) interposed between them, and are accommodated in a battery case (4) together with electrolyte, corona discharge treatment is performed on the positive electrode material (1a) or the manufactured positive electrode plate (1). Improved affinity between the positive electrode material (1a) of the positive electrode plate (1) and the electrolyte shortens the pouring time of the electrolyte and enables the lithium ions (10) to easily reach the surface of the positive electrode material (1a), thereby improving the charging/discharging characteristic of the battery.
